(Phys.org) —The frictional characteristics of nanotextured surfaces cannot be fully described by the framework of Amontons' laws of friction, according to new research from the University of Bristol, published ...

Scientists have found that two-dimensional (2D) nanostructures with asymmetric design enable a new quantum mechanism, triggering the emission of tunable light at terahertz frequencies—with unprecedented ...

(PhysOrg.com) -- One of the most promising methods for increasing the efficiency of solar cells consists of coating the cells surfaces with a thin layer of metal nanoparticles. The nanoparticles scatter ...

(PhysOrg.com) -- For catalysts in fuel cells and electrodes in batteries, engineers would like to manufacture metal films that are porous, to make more surface area available for chemical reactions, and highly ...

Carbon nanotubes represent a significant departure from traditional silicon technologies and offer a promising path to solving the challenge of energy efficiency in computer circuits, but they aren't without ...

(Phys.org)—In spin based electronics the spin of the electron is used as a carrier of information. To meet the need for faster electronics, the speed must be increased as far as possible. Today, Uppsala physicists show ...

University of California, San Diego NanoEngineers won a grant from the National Institutes of Health (NIH) to develop the tools to manufacture biodegradable frames around which heart tissues  functional ...

Swiss researchers have succeeded in growing sea-urchin shaped nanostructures from minute balls of polystyrene beads using a simple electrochemical process. The spines of the sea urchin consist of zinc oxide ...

Legend tells of Greek engineer and inventor Archimedes using parabolic mirrors to create "heat rays" to burn the ships attacking Syracuse. Though the underpinnings of that claim are speculative at best, a modern-day team ...

DNA's unique structure is ideal for carrying genetic information, but scientists have recently found ways to exploit this versatile molecule for other purposes: By controlling DNA sequences, they can manipulate ...

Inspired by the structure of moth eyes, researchers at North Carolina State University have developed nanostructures that limit reflection at the interfaces where two thin films meet, suppressing the "thin-film ...

Moore's Law - which holds that the number of transistors on an integrated circuit, and hence its processing power, doubles every 18 months - has been the guiding principal of chip design for almost half a ...

Designing new materials depends upon understanding the properties of today's materials. One such material, Nafion, is a polymer that efficiently conducts ions (a polymer electrolyte) and water through its ...

(PhysOrg.com) -- While most people know of DNA as the building blocks of life, these large molecules also have potential applications in areas such as biosensing, nanoparticle assembly, and building supramolecular ...
